Answer and Explanation:
Warm air tends to rise, and cold air tends to fall, consequently, the hot air of the equator rises and at the same time the cold air of the poles descends to the ground. This generates wind currents that displace heat throughout the atmosphere.
The movement of water creates ocean currents that transport energy heat up the biosphere. Surface ocean currents heat or cool the air above
Answer: Its answer C: A wheelbarrow is more difficult to move as More objects are placed inside.
Explanation: The greater the mass of the object the more force is needed to make it move.

<u>Answer:</u>
False, Four seismometer statitons are no required to find the earthquake's epicenter.
<u>Explanation:</u>
The least number of seismometer stations sufficient for finding the epicenter of earthquake is three. Epicenter is point on earth's crust from where the seismic rupture gets originated. Using the distances to the epicenter from atleast three seismometers the epicenter of earthquake can be determined. This distance is used as the radius and 3 circles are drawn. The point at which the 3 circles intersect is called as epicenter of the earthquake. With one seismometer station, we can determine only the distance to the epicenter. With two seismometer station, measurements are ambiguous. Using more than three seismometer stations produces redundant information. Hence three seismometer is sufficient to determine the epicenter of earthquake.
Answer:
640 J
Explanation:
At constant pressure, work = pressure * change in volume.
First, let's convert to SI units.
200 kPa = 200,000 Pa
3.4 L - 0.2 L = 3.2 L = 0.0032 m³
Therefore:
W = (200,000 Pa) (0.0032 m³)
W = 640 J
